No. 703,799 and No. 764,479, granted to me tively. A The object of thepresent invention is to ovide a new and improved hand school oom,arranged to permit the weaver to qlpickly andconveniently 0 en andchange t e shed for the passage 0 the shuttle or needle used forcarrying the weft through the open shed. r

The invention consists of novel features arts andcombinations of thesame, whic will be more fully described hereinafter and then pointed outin the claims.

A practical embodiment .of the invention is represented in theaccompanying drawings formimg a part offthis speclfication, in whichsimilar characters of reference indicate corres onding parts'in all theviews.

're 1 a plan viewof the improvement; Fig. 2 is aside elevation of thesame;

Fig. 3 is an enlarged sectional side elevation of theimprovement,.showingthe heddle in one positlon for h'oldiriglthe shedopen, and

Fig. 4 is a like'view of e same, showing the heddle in another positionfor changing the tion.

side bars A, connected with each "other by the aced'slots or notches thestrands'of the warp C, also engagedby the slots of the lay D used forbeating ulp the weft E, inserted t e warp byaneedle or manipulated bythe weaver. The loom so far described is the same as illustrated anddescribed-in my prior patents The strands'of the wa :0 are engaged byddle G, in the form I .on the sides A, A of. theloom frame, the heddle,being located 'refembly immediately in the as plainly ind cated in onJuly 1, -190 2, and July 5, 1904, respec'-.

. venient Figs. 1 and 2. The heddle G is provided-on the top with s acedalternating slots or.-

notches G G or the reception of successive strands of the warp O, theslots Gr starts ing at the forward top corners of the heddle bar andextending in a rearward and downward direction, while the slots G startat .the rear top corners of the heddle bar and extend in a forwarddirection, the bottoms of the said slots G G3 being approximately in aright-angle position, one relative to the .whenin the position shown inFigs. 1, 2 .and '3, raises alternate strands of the warp (3,. .while theremaining strands of the warp are in a lowermost bottoms of the slots Gis turned into the osition shown in Fig. 4,

C osition, that is, in the and when the heddle thefi, the strands of-t ewarpG in the slots G are lowered, while the other strands are raised.Thus, in either case the alternate warp strands are raised and theothers lowered to form an 0 en shed C for the conpassage of t e needleor shuttle F employe for carrying the weft E through the open shed C" infront of the lay D, to e subsequently beatenup by the weaver moving thelay D forward.

From the foregoing it will be seen that the p weaver by alternatelyturning the heddle G, The frame of the hand loom consists of the asdescribed and illustrated in Figs. 3 and 4,

t angle one can quickly open the shed for the convenient assage of theneedle or shuttle F, to greatly acilitate theweaving operation.

By havin the ends Gof the heddle G re vided W'ltl1 eveledsurfacesarranged in armony with the bottoms of the slots G G it isevident that a positive raising and lowering of the corresiponding warpthread takes place whenever e position of the heddle G 1s changed,.asabove explained Having thus described m invention, I

claim as new and desire to secure by Letters Patent:

. 1. A loom provided with a heddle in the form ofa bar havin spacedslots for the passage of the Warp t eads, the bottoms of successiveslots-being inclined in opposite directions.

2. A loom provided with a heddle in the A form of a bar having spacedslots for the passage of the warp threads, alternate slots beinginclined from the front top corner of the bar rearwardly, and theremaining slots be- -ing inclined from the rear top corner of the barforwardly.

3. A loom having a frame provided with means for supporting the warp,and a heddle mounted to rock on the sides of the said frame and havingspaced slots for engagement with the warp threads, successive slots Aimsfor forming open sheds for the passage of the weft.

4. A loom comprising a loom frame provided with'means for supporting thewarp,

and a heddle bar having spaced slots for enagemenkwith the war threads,the slots aving their bottoms inc 'ned in opposite directions, the endsof theheddle bar being mounted to rock on the side bars of the said loomframe and having fiat surfaces adapted to rest alternately on said sidebars.

5. A loom comprising a loom frame provided with means for supporting thewarp, and a heddle bar having spaced slots for engagement-with the warthreads, the slots 'aving their bottoms inc ed in opposite directions,the ends of the heddle bar having bevels extending in o positedirections and approximately a-ralle with the bottoms of the said slots,t e said bevels being adapted to rest alternately on the sides ofthesaid loom frame.

i 6. A loom provided with a hand heddle comprising a rectan ular barhavingl spaced slots in its top for t e passage oft e warp threads, thebottoms of successive slots being inclined in o posite directions andextending. approximate y at ri ht an les to each other,

the ends of the hedd e bar eing reduced and provided at theunder sidewith beveled s'uraces extending in o posite directions.

7. A loom providbd with a heddle comrising a rectangular bar havingspaced slots 1n its top for engagement with the warp threads, successiveslots having their bottomsinclined in op osite directions and arrangedapproximate y at right angles to each the under side with bevelsextending in opposite directions and approximately at right angles oneto the other, one of the bevels being parallel with the bottoms ofalternate slots and the other bevel being parallel to the bot-. toms ofthe remaining slots.

8. A loom provided with a heddle in the form of a bar, arranged toengage the warp threads a1. ll hold alternate warp threads up and theothers downfor formln an open shed, the ends of the heddle bar icing proother, the endsof the bar being provided at vided. on the under sidewith beveled surtop corner of the" bar rearwardly and down wardly andthe remaining slots being inclined from-the rear top corner of the barforwardly and downwardly, thev ends of the heddle bar being mounted torock on the side bars of the frame, and having on their underside flatsurfaces extending at right angles to .each other and adapted to restalternatel on the said side bars.v
